Thomas Aquinas, on Ps 49:2

“Out of Sion the loveliness of his beauty.”

“The order of the calling is set forth when he says, "Out of Zion is the beauty of his comeliness"; as if to say: this calling began in Zion. Is. 2: "Out of Zion shall go forth the law," etc. For the apostles, when they received the Holy Spirit, were in Zion, and then they were made strong to go throughout the world. Out of Zion, therefore, where the apostles were, began to be spread abroad the beauty of his comeliness. But Christ indeed began to some extent to be made known; but his beauty was not seen, because he was surrounded with weakness, because "we saw him the last of men, a man of sorrows," as is found in Is. 53. But after the Passion, his power and authority appeared.”
